Sometimes, we are just waiting for a spark. From Billie Holiday to Bruce Springsteen, Bob Marley, John Lennon or Lady Gaga, from “Bella Ciao” to “Alright”: spanning more than half a century, continents and languages, music in the modern world has shaped moments and movements in ways few other art forms can. With music, there is no place we can’t go. No truths too hard to tell, no stories too difficult to sing. This book is about impact. The moments when songs shifted thinking, spurred action, or gave people a voice they didn’t know they had.
